For the sixth year running ERM Power's Australian retail business has retained its number one ranking for customer satisfaction.

ERM Power is the second largest electricity provider to commercial businesses and industrials by load with operations in every state and the ACT. The company also sells electricity in the US and operates gas-fired peaking stations in Western Australia and Queensland.

Since mid-2016 the company has been in negotiation with developers for the purchase of large-scale generation certificates and will commence in 2018, though project details remain confidential.

33. SILVER CHEF (SIV)

SINCE we last profiled Silver Chef, the company has been through some turbulent times with a new CEO in Damien Guivarra (replacing Allan English) and a hit to profits because of fraudulent practices by equipment vendors.

Silver Chef is a hospitality funding business, and the fraud came in the form of around 60 small contracts in Victoria and New South Wales at less than $60,000 each and involved a customer applying with a fraudulent identity and using a fake vendor.

The share price took a hit, along with half year profit which dropped from $7.6 million to $6.9 million.

To tackle the fraud, the company has implemented "advanced identity verification software" and increased its investment in internal audit and risk resources.

Group revenue actually rose by 36.8 per cent and despite the controvsersy, many analysts see real potential in SIV.

34. SUNLAND GROUP (SDG)

SUNLAND Group, one of Australia's most high profile developers with the Q1 and Palazzo Versace Hotel in its folio, launched a share buyback scheme to shore up capital as it continues with several large developments on the Gold Coast and Sydney.

The buyback program halved the number of shares on offer and boosted its capital base as the property developer reported a $5 million profit in the first half of the 2017 financial year, up 45 per cent on the previous corresponding period.

However, Sunland's managing director Sahba Abedian believes the group's earnings are weighted more to the second half of the year thanks to the firm's development of a Brisbane CBD high-rise.

Three new major projects were launched in the first half of the year, including The Lakes Residences and Marina Concourse on the Gold Coast, and a 79-home development on Sydney's Northern Beaches at Warriewood. Six new projects are in the works for the second half of FY2017.

35. IMPEDIMED (IPD)

IMPEDIMED suffered another loss this year which can mostly be attributed to an increase in research and development related expenses for the company's next-gen device, Sozo.

CEO Richard Carreon called Sozo a "game changer" as the device monitors fluid changes in the body which can help manage chronic health issues like heart failure.

The company's other units performed well. The Medical Unit generated $700,000, Oncology generated an increased rate of revenue of 43 per cent, and Wellness related revenue increased by 33 per cent. The Test & Measurement revenue decreased by 50 per cent.

Impedimed also signed development deals including a three year joint agreement with Mayo Clinic to advance new solutions for ImpediMed's fluid status and body composition monitoring technology, along with partnerships with Redox and Vanderbilt University to assist the company with the development of the SOZO device.

36. DATA#3 (DTL)

A MAJOR shift in strategy from a product based approach to a service approach through its cloud based solutions has delivered the company some solid results in 1H17.

The IT giant counted the Victorian SES as one of its major successes, deploying a hybrid cloud solution for the rescue organisation which is designed to help it become more agile and efficient in responding to emergencies.

Its 1H17 results were substantially ahead of the previous corresponding year, with revenue increasing by 10.6 per cent from $457.5 million to $506 million.

Cloud based revenues were a big success for the company, earning $58 million in revenue.

Apollo picked up Apollo Motorhomes for $16m and a 100 per cent shareholding in Apollo Finance for $500,000 as its main business base and also acquired Sydney RV Group Pty Ltd, a major new and used caravan and motorhome retailer in New South Wales for $1.75 million.

The market also reacted well to its investment in Camplify, an online RV and caravan sharing community that connects owners with potential renters.

Apollo will also open two new rental locations in New York and Orlando in the US.

In its first half year report, the company reported a modest profit of $3.6 million but generated a healthy $75.4 million in revenue and is forecasting at least $12.4 million in net profit after tax for the full financial year 2017.

40. REEF CASINO TRUST (RCT)

CAIRNS casino operator Reef Casino Trust has been carrying out major renovations at its main property in the north Queensland city which hit the company's bottom line by $3 million.

RCT, which owns the Cairns casino and a Pullman Hotel, reported a net profit of $5.95 million with a distributable profit for the calendar year 2016 of $11.9m.

The company has been busy in 2016. The $6.5 million refurbishment of the Reef Hotel Casino included a new bar and live entertainment venue, a new reception area, an interactive high-tech casino lobby feature, a new lobby, an improved restaurant, and general refurbishment.
